Subject: [PATCH 0/2] perf/x86: Add ability to sample TSC
Date: Thu, 19 Feb 2015 14:11:08 +0200	[thread overview]
Message-ID: <1424347870-8492-1-git-send-email-adrian.hunter@intel.com> (raw)

Hi

With the advent of switching perf_clock to CLOCK_MONOTONIC,
it will not be possible to convert perf_clock directly to/from
TSC. So add the ability to sample TSC instead.


Adrian Hunter (2):
      perf: Sample additional clock value
      perf/x86: Provide TSC for PERF_SAMPLE_CLOCK_ARCH
